When an incident expands, what principle typically applies?

When an incident expands, the principle that typically applies is that only the functions and positions necessary are filled. This approach is rooted in the concept of scalability and flexibility that underpins effective incident management.

In times of expanding incidents, resources can become stretched and complicate operations if every position and function were to be filled without necessity. Instead, the focus should be on filling only the roles that are essential to meet the specific needs of the incident at hand. This allows for a more efficient allocation of personnel and resources, ensuring that the response remains effective without unnecessary strain on the incident management system.

This principle aligns with the Incident Command System (ICS), which emphasizes the importance of matching personnel to operational demands based on the size and complexity of the incident. By concentrating on essential functions, the response can remain agile and effective, allowing for adequate management of resources and minimizing redundancy in operations.
